Was wondering if anyone could forward a digital piture, or diagram of the exhaust riser from the universal m25 exhaust manifold, up, over and down to the muffler. Mine looks very odd (bought the boat a month ago), 2-3 45% turns in the galvanized pipe with openings covered by rubber exhaust hose and clamps. I have a fix in mind, but wonder what it looked like originally. Any help would be appreciated.
